Benefits of technology

[0010]Embodiments thus also provide a simple, rapid, and low cost approach of fabricating a compact multiplexed electrospray nozzle that includes a distributor electrode that includes the linear or area emitter source array using a precision computerized numerical control (CNC) machining platform. In comparison with silicon micro fabrication, the precision computerized numerical control machining platform process offers the flexibility of fabricating high packing density electrospray nozzle devices from a wide range of materials beyond silicon, including metals and polymers. Additionally, with CNC machining electro spray nozzle arrays can be manufactured t

Embodiment Construction

1. GENERAL CONSIDERATIONS

[0027]Embodiments provide a multiplexed electrospray nozzle for use within a multiplexed electrospray apparatus where the multiplexed electrospray nozzle may include a stepped slotted extractor electrode with respect to a plurality of distributor electrode emitter sources. Use of such a stepped slotted extractor electrode with respect to the plurality of distributor electrode emitter sources provides the multiplexed electrospray nozzle and the multiplexed electrospray apparatus with enhanced performance, and in particular increased resistance to clogging of the stepped slotted extractor electrode. The stepped aspects of the stepped slotted extractor electrode (which is thinner nearer and surrounding the slot and thicker further from the slot) allow for optimization of electric field (due to thinness nearer and surrounding the slot) within the context of mechanical stability (due to thickness further from the slot).

[0028]For example, FIG. 8A shows an image of...

Abstract

A multiplexed emitter source distributor electrode, a related multiplexed electrospray nozzle, a related multiplexed electrospray apparatus and a related coating method that uses the multiplexed electrospray apparatus are all predicated upon at least one of: (1) a linear emitter source density greater than about 15 emitter sources per centimeter; and (2) an area emitter source density greater than about 225 emitter sources per square centimeter. The distributor electrode comprises other than a silicon material (i.e., a metal, metal alloy, ceramic or polymer material). The distributor electrode may be fabricated using a computerized numerical control method that provides the coating method with enhanced uniformity. The nozzle and the apparatus may also use a stepped slotted extractor electrode.
